Effects of preoperative low-intensity training with slow movement on early quadriceps weakness after total knee arthroplasty in patients with knee osteoarthritis: a retrospective propensity score-matched study

Table 5 Factors independently influencing changes in quadriceps strength and TUG in all participants (independent variable: thigh swelling)

Dependent variables	Independent variables	Standardized β coefficient	p
QW	Age (year)	0.08	0.31
	Tourniquet time (min)	−0.04	0.56
	Thigh swelling (%)	−0.24	0.00
	ΔKnee pain during the QST (mm)	−0.16	0.04
ΔTUG	Age (year)	−0.03	0.64
	Gender	−0.07	0.36
	Thigh swelling (%)	−0.06	0.45
	QW (%)	−0.30	0.00

Note. N = 173, male = 44. Standardized β indicates the adjusted regression coefficient. The Δ symbol indicates pre- and postoperative measurement changes
